Patent CA-2064213-C (CA)
Title: Micro-machined accelerometer with tilt compensation
Inventor: HENRION W S
IPC: F16F15/073
Filed: 1990-05-25
Granted: 1997-03-25
Abstract: A spring-mass-support structure (36') is arranged as an accelerometer with two electrostatic feedback loops so as to mea-sure two components of acceleration. Two of such accelerometers (1010, 1012) are advantageously used on a submerged platform (1006) to determine the direction of a sound source in a body of water. One of such feedback loops (924, 926, 928, 930, 932) of each accelerometer is used to measure low frequency gravitational acceleration applied to the platform as a result of the tilt of the platform due to the action of current and wave action of the water. The other of the feedback loops (124, 126, 150, 164, 166) of each accelerometer measures sound wave induced acceleration on the platform. The gravitational acceleration of each acceler-ometer is used to compensate the higher frequency acceleration for the effect of tilt of the platform.

Title: King roll reeling machine
Inventor: SCHONMEIER HERBERT
IPC: B65H18/20
Filed: 1991-08-16
Granted: 2004-04-06
Abstract: The known king roll reeling machines for shaftless winding of a web of material (4) divided by a lengthwise cut, in particular a web of paper of cardboard, onto sleeves (11) have take-up rollers (6) which are applied during take-up to two king rolls (2, 3) and are supported by guide heads (10) which can be inserted sideways into the sleeves of the two outer take-up rollers (6). The take-up rollers (6) can only be wound with high winding quality up to a maximum diameter. According to the invention, the space delimited by the king rolls (2, 3) and the take-up rollers (6) is sealed and an overpressure is produced in the space. To this end, sealing elements (18) which can be displaced axially to suit webs of different widths and which can be moved simultaneously in an area outside the area of movement of the guide heads (10) and their fastener (carriage (9)) are arranged in the region of the two side ends of the king rolls (2, 3). Frictional engagement between the king rolls is prevented when the sealing elements (15, 18) are in the sealing position.

Title: Sawmill method and apparatus with movable scanning means
Inventor: CARTER MARK L
IPC: B27B27/00
Filed: 1993-03-30
Granted: 1999-08-31
Abstract: A flitch or cant is successively transported by a pair of differentially operated clamps, first to a scanning station, and then to a sawing station where the wane is removed. A series of flitches are processed in this manner such that as the wane edge from a first flitch is sawn, a next flitch in succession is optically scanned. The sawing and scanning is accomplished by means of a combination saw and scanner which moves in a direction longitudinal of the flitch as respective flitches are held in stationary positions at the sawing station and at the scanning station. Between passes of the saw-scanner combination, the sawn flitch is conveyed away and the next flitch in line is conveyed forwardly to the sawing position while being skewed by the clamps in accordance with the characterization generated by the scanner.      The scanner extends outwardly from the side edges of the flitch to provide a radiation beam directed obliquely inwardly and downwardly from a point displaced along the flitch from the location where the radiation image intersects the flitch and provides a line image. Television cameras also disposed to the side of the flitch view the line image at an oblique angle, but the cameras are positioned along the flitch in a second direction opposite the direction where the radiation source was located. The cameras "see" the line images on the side edge of a flitch substantially face on.

Inventor: LAPLANTE BENOIT
IPC: B65H26/08
Filed: 1993-05-28

Abstract: The method is for producing a first primary roll having a predetermined lateral surface defined by a diameter Df.   The primary roll is made of material wound around a spindle.  The material is used to produce smaller secondary rolls of material.   The method comprises  steps  of  (a) calculating a portion Sf of the lateral surface, which is covered by the spindle; (b) calculating a portion Si of the lateral surface, which represents material needed to produce the smaller secondary rolls of material: (c) calculating a compression factor K1 which is derived from a compression rate K of a previous second primary roll used to produce previous  secondary  rolls  with  respect  to  the  previous secondary rolls; (d) calculating Df where:                                 (e) winding up material around the spindle to produce the first primary roll until a diameter of the first primary roll reaches said diameter Df; whereby loss of material is reduced by taking into account compression factor K1 which varies with respect to time.  An apparatus to perform the present method is also provided.

Granted: 2004-06-01
Abstract: An image acquisition system includes a transport mechanism for transporting sheets of objects past a sensor. The sensor scans the objects and generates data streams which are scaled by a multiplier to compensate for the speed variation of the transport mechanism. At speeds much lower than a nominal speed, the scanning rate of the sensor is increased to generate several data streams for each scanned line, which are then combined in a single speed corrected signal stream for further processing.

Inventor: BANTING JOHN F
IPC: G01R19/165
Filed: 1994-04-07
Granted: 2003-01-07
Abstract: A faulted circuit indicator with a high visibility spherical display device is disclosed for indicating a fault condition.     Disposed within the display apparatus is a permanent magnet 42 that is in magnetic communication with, and actuated by, an electromagnet. The permanent magnet is rotatably mounted within the display and is attached to a spherical flag. The spherical flag has two different colors at its hemisphere to represent fault and no-fault conditions. The electromagnet comprises a magnetic core and coil assembly and is magnetized by a current pulse received from the indicator circuitry. By changing the direction of the current through the coil assembly, the polarity of the electromagnet is reversed, which in turn causes the permanent magnet to rotate 180° to realign with the poles of the electromagnet. Because the flag is colored about its hemisphere, the rotation of the permanent magnet results in a change of color being displayed in the display device.
